(BCN) — Though brief, the life of Jordon Almgren, who was fatally stabbed in his Discovery Bay home last weekend, was full of friends and great experiences, his father said today.

The 9-year-old had a particular penchant for baseball and played on the Brentwood Pony Baseball League on the Mustang-9 Angels team, according to the league’s website.

“Though he’s no longer with us, he’s still an Angel looking down on us,” Jordon’s father Jon Almgren said in a news conference held this afternoon outside of the family’s home.

The boy was killed in a stabbing reported around 10 a.m. Sunday. Authorities have arrested a family friend, William Shultz, 18, who is facing charges of murder with a lying in wait enhancement and urglary.

Shultz, who appeared in court for the first time on Wednesday but did not enter a plea, is friends with Jordon’s older brother and had been at the Almgren home Saturday night, the family’s attorney Michael Verna said.

Jon Almgren described his son as an “enormously friendly, happy and welcoming boy, who considered his friends to be extended family.”

“With Jordy’s memory in our hearts, we will continue to offer our love and our home to our family, friends and our children’s friends, because we know that’s what Jordy would have wanted us to do,” Almgren said.

Almgren declined to comment on the events that led to his son’s death sometime early Sunday morning.

“He was a wonderful boy and we will miss him dearly,” Almgren said.

On Saturday, Shultz’s family requested sheriff’s deputies to evaluate their son’s mental health. Although he didn’t meet the criteria to be placed on an involuntary mental health hold, Shultz agreed to be hospitalized voluntarily, a sheriff’s spokesman said.

He was released later Saturday and got into a fight with his mother before going over to the Almgrens’ house to spend the night.

The family was unaware of Shultz’s history with mental illness and did not know he had spent time with a psychiatrist on Saturday, according to Verna, the Almgrens’ lawyer.

Verna declined to say whether the family would be pursuing additional legal action.

The Almgren family extended their thanks to the Discovery Bay community for the outpouring of support they have received in the past few days.

“We are blessed to live in a community that comes together in times like these,” Almgren said. “We very much appreciate the prayers, kind words and thoughtfulness of our friends and family and complete strangers who have helped give us strength and solace.”

A public service for Jordon is scheduled for May 8 in Brentwood.

A GoFundMe campaign has been established to help the family pay for expenses related to Jordon’s death and can be found at http://www.gofundme.com/t32awz4.

On Sunday, during the San Francisco Giants’ game at AT&T Park against the Los Angeles Angels of Anaheim, team officials are expected to publicly remember Jordon’s life.
